SPECIFICATION forming part of Letters Patent No. 396,053, dated January 8, 1889.

Application filed September 8, 1888l Serial No. 284,868. (No model.)

To @ZZ whom it may concern:

Be it known that I, ISAIAH SHARP, a citizen of the United States, residing at Redkey, in the county of Jay and State of Indiana, have invented certain new and useful Improvements in Steam-Generators; and I do declare the following' to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying' drawings, and to the letters and figures of reference marked thereomwhich form a part of this specification.

This invention relates to steam-generators and feed-cooking devices; and it consists in certain improvements in the construction of the same, as hereinafter described and claimed.

In the accompanying drawings, Figure l represents a front view of the device. Fig. 2 is a vertical central section of the generator.

A designates the main casing of the generator, which is cylindrical in form,and B represents a taperingl :flue placed within the casing, a water-chamber being' thus formed around the said flue.

C indicates a double ring, which forms a base for the said main casing and flue, said ring being formed with an inclined inner part, c., which is rigidly connected with the Outer vertical part of the ring, a seat or groove being' thus formed in which the lower edges of the casing and tine are brought together and rest.

The upper edge of the casing A is turned outward to form a fia-nge to receive the top plate, D, which covers the boiler and lits around the tine B. The said top plate is formed with an inclined inner ring, b, which fits on the flue B, and a ring, c, which sets against the inside of the casing A, and is formed with a flange, c, which extends over the casing, as shown. A ring, d, is placed on the outside of the casing opposite the ring c, to which it is bolted, and a ring, f, is iitted within the line B, opposite the ring l), the two rings b and f being secured together by bolts. A safety-valve, g, to the boiler is seated in the top plate, and three steampipes (indicated severally by h L) communicate with the boiler through the said plate.

E indicates the door through which the fire-chamber is charged with fuel, The dooropening is provided with three plates or frames to 'form a passage through the waterchamber to the combustion-chamberan.

outer frame, 7.1', to which the door E is hinged, a frame, le', fitting between the casingAand the flue B, and an inner frame, k2, against the inner side of the flue. ihese frames are fastened by bolts passed through them and through the casings of the boiler and the flue, and are provided with suitable packing, so that a steam-tight passage is lformed through the water-chamber to the combustion-chamber.

F indicates the g'ratc, which is loosely pivoted on a bar which extends across and is supported by the base-ring C. The grate is provided with a handle, which is turned down and extended through a slot or draftopening in the base-ring. site the draft-opening, is secured to the gratehandle and serves as a damper.

G indicates the ash-pan, which is bolted to the ring C, and is provided with a sliding door, m.

The pipe 7L is an outlet :for steam when it is desired to use it otherwise than in the barrel or feed-receptacle. The pipe 7L extends from the top of the boiler to a barrel or other receptacle for :feed to be steamed.

rlhe legs s are secured in grooves to the base-ring C. The casing A and flue B are riveted together at the base, where they rest in the groove in the base-ring', the joint being' made steam-tight, and suitable packing is used, preferably asbestus, in securing the top plate, D, to the casing and iiue.

I claiin- The combination, with the casing A and tapering tine B, of a top plate provided with a central opening and formed with a flanged ring, c, and an inclined ring, I), fitting' around the Hue, an inner ring, f, tted within the flue, and a ring, d, secured outside of the casing, substantially as set forth and described.

In testimony whereof I my signature in presence of two witnesses.
